1988 Map of Shinumo Altar

USGS Topo · Published 1988

About this map

The Shinumo Altar formation dominates the high desert terrain of the Navajo Indian Reservation in northern Arizona as recorded in the late 1980s. This survey illustrates a complex landscape of erosion and water management, where numerous drainages like Hogansaani Wash and Shinumo Wash carve through the Eminence Break. The land is characterized by massive sedimentary layers, forming distinct features such as the Gray Grass Bench and Limestone Ridge. Water security in this arid environment is evidenced by man-made infrastructure like the Salt Reservoir, Second Reservoir, and Corner Rock Reservoir. These sites, along with names like Rock Corral Bench, suggest a history of seasonal livestock grazing and land use. The southern portion of the map transitions into the higher elevation of Bodaway Mesa, marked by prominent landmarks like Tooth Rock and Corner Rock.
